Enabling technologies for matrix converters in aerospace applications

Abstract

The matrix converter is a direct AC-AC power converter topology that does not contain an intermediate DC-link stage. This paper presents different enabling technologies to enhance the suitability of the matrix converter topology for aerospace applications. The use of silicon carbide power devices to improve efficiency and reduce system weight together with an improved, high speed fault detection technique are presented. Results from different prototype matrix converters to validate the concepts are also presented.
